Re: Wind Load Topographic Effects

Conrad
 
Now the tough question if you have a rectangular building say 20 x 40ft.  When you calculate the wind load for the long side do you use 40' or 44.7' ??   Then what is length for the short side 20' or 28.3' ??
 
I am not sure for short direction. any ideas ?

My Understanding is that the quadrant is 90 degrees. But need to draw two orthogonal axes for the building, and 8 cardinal/compass directions for the wind. The 4 orthogonal directions then experience the maximum wind in the quadrant defined by 45 degrees either side of the orthogonal axis.
